Correlation between urinary osmolality and release of uEV-AQP1 or uEV-AQP2. The relationships between urinary osmolality and release of uEV-AQP1 (a) or -AQP2 (b) for all samples (on days 1, 2, and 6) are shown. The line is the least-squares regression line. n and r indicate the number of individuals and the correlation coefficient, respectively. There is a significant correlation between urinary osmolality and the release of uEV-AQP2, but not that of uEV-AQP1 (Pearson analysis, P < 0.01)
